A guidebook to trekking the 748km (465 mile) Pyrenean Haute Route (Haute Randonnée Pyrénéenne, HRP) along the France–Spain border. Suitable for fit experienced trekkers comfortable with mountainous terrain, this challenging unwaymarked route traverses the Pyrenees from sea to sea, from Hendaye on the Atlantic Coast to Banyuls-sur-Mer on the Mediterranean, with the aim of staying as high as possible.

The PHR is divided into 44 graded stages of 8 to 28km (5–17 miles), nearly all ending at overnight accommodation. These are presented in 5 sections, which can be accessed by public transport, for the benefit of those wishing to trek only part of the route. Also included are optional ascents of 10 classic summits, including Vignemale, Le Taillon and Pico de Aneto.
